Problems distributing game with PhysX

Hello,
I created a small game using PhysX engine. I packaged and I sent the game to a friend of mine.
He copied game directory in his computer, and when he launched the game he got:



He reinstalled drivers, and he even tried to copy physx.dll in the same dir of the game, but.... nothing!
He cannot use the game.

Please help me! Maybe I missed somthing during the game distribution?

thank you for your support!

Update: My error is regarding ackphysX.dll




But I get a dialog-box error:

Hi!

Today I've tested a small PhysX-Level on my PC at work. I get the same error.

I think it depends on the hardware. At home I use a Gefore 9600GT, a work I had a 7200SE. This card had no PhysX-GPU: http://www.nvidia.com/object/physx_gpus.html

Seems there is no fallback-code like a emulation or use the CPU for the calculation.

Hi!

A while back I was having problems when it came time to play
the .exe game.

The problem at that time was my anti-virus. It removed the vital part
of the game thinking that it was a virus.
If this is the case in your situation, you will have to tell
your anti-virus not to remove the file.
